Gage Certification

Gage certification is the foundation of a gage surveillance program. Gage surveillance is simply an orderly system of keeping records on gages and gage wear. PG&T supplies long form certification for new gages and masters. Each gage receives a dedicated I.D. number.  An assigned PG&T number will be used if a number or other type of mark is not designated or requested at the time of purchase.

Re-Certification

Sometimes a customer’s gage is found to be out of tolerance. A customer is give the option to purchase a new gage or have their gage repaired or corrected where applicable.

If the customer chooses not to repair their gage or their gage is deemed too costly to repair, the gage is returned to the customer with an inspection report . Gages returned in these instances are not re-certified.

Long Form Certification

  • Long form certification certifies the actual measurement of all specific critical dimensions and critical characteristics for a particular gage.
  • One gage per long form certification. (See certification marking).
  • This certification also provides certification of NIST* trace-ability

  • Name and address of organization providing the certification

Important Facts About Gage Hardness
A gage that is softer than the part it gages may fail. After multiple applications a “too soft” steel gage may become nicked, distorted and worn out. For maximum wear life, PG&T gages are made from the highest quality materials. You’ll always have a greater payback with PG&T.
